Hi,Can the VPS_TX pin be powered with a voltage different from VPS? Specifically, can you connect VPS_TX to 5 V while VPS is at 3.3 V?I think it should work, but I would like your confirmation as I couldn't find this information in the datasheet.Than...
Hello ST Community,We are developing an iOS application using the ST25SDK (Swift) to interact with a device equipped with the ST25DV02K-W1 (Dual Interface EEPROM).Our Goal: We need to configure the PWM parameters to control an Adjustable Output Curre...
It is getting hang at this point, going to infinite loop MCU: STM32F407SPI1 InterfaceTried ST25R_SELFTEST as well same problem
Hi, we use the ST25DV16KC and for development i use the ST25R3911B. Problem is: ST25R3911B connected via micro usb to the pc. so far looks good Pressing the TAG Editor Button I just want to read the config: Pressing Button Read Configuratio...
I am testing power consumption. The hardware is using nucleo-L476 and X-NUCLEO-NFC08A1, and the software is using the NFC06A1_PollingTagDetect routine from X-CUBE-NFC6. The test revealed that the average power consumption was 180 uA when entering the...
I am using ST25R3916B with differential antenna without varicaps.The antenna is configured to receive maximum signal from the smartphone on the RFI1.There is a TFT display between the antenna and the smartphone. The smartphone reads the tag with gre...
Hello, everyone!My project consists of creating a sensor system that works with NFC. It will be a TAG with the st25dv04k chip, which will power a set of chips through Energy Harvesting. The reader system consists of the ST25R300, chosen for its trans...
Hello everyone,I am developing an iOS application using the ST25SDK (converted/wrapped for Swift) to interface with the M24LR16E-R Dynamic NFC Tag.I am facing a blocking issue where any attempt to call readBytes() (which is used in TagReadMemoryGenVi...
I am entering the world of NFC with a somewhat complex project, but I took the initiative to start it. The goal was to create a sensor that would work only with Energy Harvesting from the reader.For this, I chose the ST25R300 chip to be the chip for ...
Hello,I currently working with the STEVAL-25R3916B kit and using the ST25R3916 GUI to tune the antenna. My goal is to achieve a target amplitude of 2600 mV or higher, but the system remains around 2 V even when 5 V is selected for RF power on the rea...
